Age
Relative age dating of the Hamilton places it in the middle and lower Devonian period. In Maryland, it rests conformably atop the Tioga Metabentonite Bed of thinly laminated shale with a thickness less than one foot over the Needmore Shale, and conformably below the Brallier Formation (formerly Woodmont Shale) dark laminated shale in the east, Harrell Shale dark laminated shale in the west, and Tully Limestone in the subsurface of Garrett County. In Pennsylvania it lies atop the Onondaga Formation limestone and shale forming a sharp conformable contact with the Selinsgrove Limestone of that formation, and lies beneath the Portage (Brallier, Harrell, Burket) dark shales of the Harrell Formation.

Famous quotes containing the word age:
“And men left down their work and came,
And women with petticoats coloured like flame.
And little bare feet that were blue with cold,
Went dancing back to the age of gold,
And all the world went gay, went gay,
For half an hour in the street to-day.”
—“Seumas” “O’Sullivan” (1879–1958)
“When women reach the age of maturity, Mother Nature sometimes overworks their frustration to the point of irrationalism. Like the middle-aged man...who finds himself looking longingly at a girl in her early twenties.”
—Mark Hanna, and Nathan Hertz. Dr. Von Loeb (Otto Waldis)
